Application filed June 29,

This invention relates to dumping tables for usein loading tram carswith railroad ti 7 The device is particularly designed use in loading ties from the piles in the storage yards of woodpreserving plants. lirsucli yards the ties are arranged in piles, from which they transterred to train cars arranged to carry loads, which are of such shape that the train cars. with their loads of ties can lie-pushed into the cylinders in which they are subjected to the preservative treatment. The dumping'table, according to this invention, is located on or near a railway track passing between the piles of ties, the tram cars to lee-loaded being on an adjacent track. A traveling crane on the first track picks up a number of ties which are then deposited on the dumping table, from whicn they are transferred to the tram cars, on which the load is formed by specially an ranged forms and held in place by the usual bails secured to bolster arms on the tram cars. See e. g. Patents No. 1,428,454, No. 1,510,202 and 1,528,041.

The dumping table is particularly designed to facilitate this transfer with a minimum of manual labor. The construction of the dumping table and the manner in which it is used will be readily understood from the accompanying drawings in which Fig. 1 is an elevation, parts being shown in section;

2 is a plan of Fig. 1;

3 is an elevation at right angle to that 0t Fig. 1, the trainee and former device being omitted;

F is a plan of the arrangement for raising and lowering the roller frames; parts hein broken away;

Fig. 5 is a side view elevation of Fig. i;

Figs. 6, 7 and 8 show details.

The whole device may be and is preferably mounted on a wheeled truck, so that it may be moved along the track. Supported on these wheels is a strong framework of wood and metal, the details of which are not essential, and will readily be understood from the drawings. Supported on this framework are downwardly inclined skidways 5, 5, here shown as lengths of railroad rails. These skidways slope at any convenient angle, as shown, and the rear-ends are turned up to prevent the ties from slipping oil the back end. Arranged between the skidways are 1827; Serial no. 202,312.

The bearing. plates 11, as shown in Fig; have atone end inclined surtaces- When the feet, 10, are in the position shown 'inliig; 5. the rolls are'helow theupper surtacesot the skid rails. When the 'lramesare moved 1on gitudinally, the feet slidelup' the inclined sur-' face and the upper rimsot'rthe rolls extend above the skid rails, as shown in Fig.52. The frames are moved longitudinally by-means 0t connecting rods '9 connected atone end: to the bottom flanges, 23, otwebs, 22, and at the other to levers 8 mounted on shafts 8 having. handles '7. Theshal'tsS are carried in bear-1 ings on fixed parts of the table. Ittwill be understood that'each side of each frame-may be provided with similarraising; and alower ing novices and thatthe crank shafts extend beyond each skid rail, so that the trames can be operated froineitherzside. Anadditional extension apron or frame l2,li'kewiseprovided with rollers, is hingedby means of: shalt 30 torthe end of the skidrails Vvlielr not in use, it can he foldedback on-thettable) lVhenwinuse, itrest-s on a .cross-bar' *13, e tending across the topsot the'postse otthc adjacent load-forming device: Elevated walkways 14- are located on each side of the table, as in operation am'an' is required on either or both sides to 'ieedth'e ties from the table to the tram cars.

In operation a vbundleot ties is gathered from the stacks of ties inttheyard' by agatlr ering cable and crane. The bundleoflties is placed on theskids of the dumping table; the roller sect-ions being depressed: belo-w't-he skidways so that this heavy load, whichimay be live or six tons, does not come directly on therollers. The tics nearest the delivery end of the table are passed by the workman over the roller apron into the tram car. As the ties are removed from the table, the-distance from tram to ties becomes greater and greater, and the roller frames can then be successively raised, to facilitate the movement of the ties from the table to the tram car. The movement is a gravity aotion and the workman onworkmen on either or both feet along the tram car track.

of the walkways merely lreeps the ties straight as they pass over the table.

The dumping table may either be mounted on a wheeled truck, as shown in Fig. 1, or metal feet 15, as shown in Figs. 6 and 7.

Then mounted on wheels a track clamp such as shown in Fig. 8 may be used. Two diverging clamping pieces 31 engage the head of the rail, and may be loosened or tightened by ring 82. These pieces 31 are supported by a plate 33, fastened as shown in Fig. 3 to the lower beam of the truck. The truck is the more convenient form, but not necessary, as the entire table could be lifted about by the traveling crane.

When the ties are to be taken directly to the treating cylinders, the loads on the tram cars must conform in shape to that of the treating cylinders, the loads being held in shape by bails, as shown in the patents abovereferred to.

In order to so shape the leads, I use the former device, shown at the right of Figs. 1 and 2, which comprises beams 34:, extending beneath the tram car track. Pairs of these beams are located at intervals of about 200 Mounted at each end of these beams are sockets 35 into which fit upright members 1, held in place by bolts. The upright-s may be braced by arms 36, engaging by means of bolts the flanges of angle pieces secured to beams 53%. Swinging arms 8 are mounted at the upper portion of the uprights 1. and have their inner sides curved to fit the desired configuration of the load on the tram car, 50, diagrammatically shown in outline.

The two members 1, on the side adjacent the dumping table, carry a cross-bar 13 on which rests the extension table 12. When the tram car is loaded it is moved forward away from the formers, the swinging arms 3 of which swing with the direction of the tram movement and offer no resistance. The bails may be placed over the load either before or after the tram is moved from the formers.

When the dumping table and formers are set up at any desired place on the tracks in the storage yard. this point is termed a load ing station, and once the loading equipment is set up, it may not be necessary to move it more frequently than once every one to three days. hen a move becomes necessary, the extension 12 is folded back on the main table, the uprights 4 and attached parts may be detached by removing the bolts connecting them to beams 34, and placed on the walkways 14-, and the table moved to the next selected station, all of which can be effected in a few minutes.

The use of the combined dumping table and load former results in notable economies in the handling of ties.

I claim:

1. A dumping table adapted for handling 2. A dumping table adapted for handling railroad ties comprising inclined skidways, means for supporting a series of rollers adjacent the slzidways, means for raising and lowering the supporting means to raise or to depress the rollers above the to as of the skidways, and a pivoted roller carrying frame mounted at the end of the skidways, the said table being mounted on a railway track, of a load-forming device located near an adjoining track, said load-forming device comprising curved arms mounted to swing on upright posts, and a cross-bar on two of said posts for supporting the pivoted roller-carrying frame.

3. The combination of a portable dumping table adapted for handling railroad ties comprisin inclined slridways having means for supporting a series of rollers adjacent the skidways, means for raising and lowering the supporting means to raise or depress the rollers above the tops of the skidwa-ys and a pivoted roller-carrying frame mounted at the end of the skidways,with a portable loadforming device having means for supporting said pivoted roller-carrying frame.

4. The combination of devices as claimed in claim 3, in which the dumping table and load-forming device are mounted on adjacent railway tracks.

5. A portable dumping table including inclined skidways, a plurality of frames movably mounted on said table and spaced longitudinally of said inclined slridways, said frames carrying rollers adjacent said skidways, means for independently raising and lowering each of said frames to thereby project the rollers thereon above said inclined skidways, and an additional roller-carrying frame eXtensibly connected to said table, said frame being movable to a position beyond the lower ends of said skidways.

6. The combination of a portable dumping table con'iprising inclined skidways having means for supporting a series of rollers adjacent the shidways, means for raising and lowering the supporting means to raise or depress the rollers above or below the tops of the skidways, with a portable load-forming device, and a roller-carrying frame supported by and adapted to connect the said dumping table and the load-forming device.

In testimony whereof, I affix my signature.
